(7) UARTB FIFO control register 1 (UBFIC1)
The UBFIC1 register is valid in the FIFO mode (UBFIC0.UBMOD bit = 1). It generates a reception timeout
interrupt request signal (INTUBTITO) if data is stored in receive FIFO when the next data does not come
(start bit is not detected) after the lapse of the time set by the UBTC4 to UBTC0 bits (next data reception wait
time), after the stop bit has been received.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.

CHAPTER 15 ASYNCHRONOUS SERIAL INTERFACE B (UARTB)
UBTC4
When counting up of the reception wait time, set by the UBTC4 to UBTC0 bits, is
complete, the count value of the timeout counter is cleared to 0, regardless of the
status of the data stored in receive FIFO. When the next start bit is later detected,
counting is started again from the stop bit of that data.
